‘I know where you live': The bike was fitted with a tracking system (Picture: Giant)

A student whose bike was stolen looks like they’ll be having the last laugh after writing a hilarious letter to the thief politely informing him that the bike has a tracker.

Bike tech company Blaze tweeted ‘this must have been the best feeling ever’ accompanied by the note, in which the theft victim cheerfully threatens the thief with a visit from her ‘majesty’s finest.’

Addressed ‘DEAR DOUCHEBAG THIEF’ the brazen note informs the thief that their face was caught on CCTV at the station and that a tracer was installed inside the bike frame after it was stolen in the past.
